Introduction

  • Target: Shared Bandwidth Package Traffic Anomalies (sBwp)
  • Challenge:
    • Large scale
    • Diversity of traffic anomalies
    • Low overhead and real-time
    • Dynamicity

  • Existing work:

    • designed for specific applications
    • require training a separate model for each user
    • not suitable for cloud network scenarios
